[REG 6.7->6.8]: Cannot read from attached 'Accessible.name' property

Repro:

Open attached example:
> qml a11y-name.qml

Click the button

It should print Accessible.name, Accessible.description and Accessible.role on the console. Clicking again will mutate those values.

In dev, this doesn't work for Accessible.name

I suspect this is a QML bug. Strangely, I see this problem only if the property is called 'name'. (I tried to rename it to 'surname', and it works again).
